What is MVVM?Why use MVVM?Demos
Starting with little Data BindingAdd More Data BindingAdd a View Model
What is MVVM?
Model-View-ViewModelModel = Data ClassView = User InterfaceViewModel (VM)
UI binds to this classVM consumes services of ModelVM may expose services/properties of Model
What is MVVM?
View knows nothing about ModelModel knows nothing about ViewModel knows nothing about View ModelView Model knows nothing about ViewCommunication from View to VM is via data binding
Lists for List Boxes and GridsIsEnabled properties for ButtonsData for Text Boxes
Why Use MVVM
Separate UI / Business / Data LogicBe able to swap out UI
Leave business rules/data logic in placeASP.NET to SilverlightWPF to Windows Phoneetc.
Unit TestingWrite less UI code
